Effect upon mortality of the extension to holidays and weekends of the "ICU without walls" project. A before-after study. / Efecto sobre la mortalidad de la ampliación a los festivos y fines de semana del proyecto «UCI sin paredes¼. Estudio before-after.

OBJECTIVE: To determine whether extension to holidays and weekends of the protocol for the early proactive detection of severity in hospital ("ICU without walls" project) results in decreased mortality among patients admitted to the ICU during those days. DESIGN: A quasi-experimental before-after study was carried out. SETTING: A level 2 hospital with 210 beds and a polyvalent ICU with 8 beds. PATIENTS OR PARTICIPANTS: The control group involved no "ICU without walls" activity on holidays or weekends and included those patients admitted to the ICU on those days between 1 January 2010 and 30 April 2013. The intervention group in turn extended the "ICU without walls" activity to holidays and weekends, and included those patients admitted on those days between 1 May 2013 and 31 October 2014. Patients arriving from the operating room after scheduled surgery were excluded. VARIABLES OF INTEREST: An analysis was made of the demographic variables (age, gender), origin (emergency room, hospital ward, operating room), type of patient (medical, surgical), reason for admission, comorbidities and SAPS 3 score as a measure of severity upon admission, stay in the ICU and in hospital, and mortality in the ICU and in hospital. RESULTS: A total of 389 and 161 patients were included in the control group and intervention group, respectively. There were no differences between the 2 groups except as regards cardiovascular comorbidity (49% in the control group versus 33% in the intervention group; P<.001), severity upon admission (median SAPS 3 score 52 [percentiles 25-75: 42-63) in the control group versus 48 [percentiles 25-75: 40-56] in the intervention group; P=.008) and mortality in the ICU (11% in the control group [95% CI 8-14] versus 3% [95% CI 1-7] in the intervention group; P=.003). In the multivariate analysis, the only 2 factors associated to mortality in the ICU were the SAPS 3 score (OR 1.08; 95% CI 1.06-1.11) and inclusion in the intervention group (OR 0.33; 95% CI 0.12-0.89). CONCLUSIONS: Extension of the "ICU without walls" activity to holidays and weekends results in a decrease in mortality in the ICU.

OBJETIVO: Estudiar si la ampliación, a festivos y fines de semana, del protocolo de detección proactiva precoz de gravedad en el hospital y actuación de intensivistas en planta convencional y urgencias (actividad «UCI sin paredes») se asocia a una reducción en la mortalidad de los pacientes ingresados en UCI en esos días. DISEÑO: Estudio cuasi experimental before-after. ÁMBITO: Hospital de nivel 2 con 210 camas en funcionamiento y UCI polivalente con 8 camas. PACIENTES O PARTICIPANTES: En el grupo control, donde no se realiza la actividad «UCI sin paredes» los fines de semana ni festivos, se incluyeron los pacientes ingresados en la UCI esos días del 1 de enero de 2010 al 30 de abril de 2013. En el grupo intervención se amplió la actividad «UCI sin paredes» a los fines de semana y festivos y se incluyeron los pacientes ingresados esos días del 1 de mayo de 2013 al 31 de octubre de 2014. Se excluyeron los pacientes procedentes de quirófano tras una cirugía programada. Variables de interés: Se analizaron las variables demográficas (edad, sexo), la procedencia (urgencias, planta de hospitalización, quirófano), el tipo de paciente (médico, quirúrgico), el motivo de ingreso, las comorbilidades y el SAPS 3 como puntuación de gravedad al ingreso, estancia en UCI y hospitalaria, además de la mortalidad en la UCI y en el hospital. RESULTADOS: Se incluyeron en el grupo control 389 pacientes, y 161 en el grupo intervención. No se encontraron diferencias entre ambos grupos, salvo en la comorbilidad cardiovascular (un 49% en el grupo control frente a un 33% en el grupo intervención; p < 0,001), en la gravedad al ingreso medida mediante el SAPS 3 (mediana de 52 [percentiles 25-75: 42-63] en el grupo control frente a 48 [percentiles 25-75: 40-56] en el grupo intervención; p= 0,008) y en la mortalidad en UCI, que fue de un 11% en el grupo control (IC 95% 8 a 14) frente al 3% (IC 95% 1 a 7) en el grupo intervención (p = 0,003). En el análisis multivariable, los 2 únicos factores asociados con la mortalidad en UCI fueron: SAPS 3 (OR 1,08; IC 95% 1,06-1,11) y el pertenecer al grupo intervención (OR 0,33; IC 95% 0,12-0,89). CONCLUSIONES: La ampliación de la actividad «UCI sin paredes» a los fines de semana y festivos conlleva un descenso en la mortalidad en la UCI
